Hi all,
  I have some questions about rtems's tcp/ip network system,please help me.
  My target is Intel PIII and the BSP is PC386 . The RTOS is the rtems-4.6.0pre3 and the network device is Intel 82559ER.
  The application is the sample netdemo,sometimes my target works very good,for example
  1. ping the pc running Rtems/netdemo that it is ok!
  2. connect using telnet 192.168.93.236 24742 that it is ok!
  3. Send a `s' command to send TCP data packets that it is ok! 
  4. Send a `u' command to send UDP data packets that it is ok!
 
  BUT,let's trouble is that my target sometimes halt.
  The information of the halt is shown in the following:
  ------------------------------------------------------------
